MACHINE FOR CRIMPING THE ENDS- OF PAPER TUBES.

SPECIFICATION forming part of Letters Patent No. 410,518, dated September 3, 1889.

I Application filed April 8, 1889. Serial No- 306,369. (No model.)

To all whom it may concern.-

Be it known that we, ROBERT KNEFF HILL and HENRY CLAY FOOTE, of \Voodbury, in the county of Gloucester and State of New J ersey, have invented certain new and useful Improvements in Machines for Crimping the Ends of Paper Tubes; and we do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvelnentin machines for crimping the ends of paper tubes; and it consists in the combination of a tubular body which is mounted upon a suitable standard, a movable table or support which is vertically adjustable upon this body, a spring-actuated treadle, a connecting-rod, and a second support placed upon the upper end of the body and which is made vertically adjustable thereon by means of the connectingrod extending from the treadle, as will be more fully described hereinafter.

The object of our invention is to provide a cheap, simple, and efiective machine whereby the ends of pasteboard tubes or packages can be crimped at both ends by a single movement of the treadle to such an extent that articles of merchandise placed in the tubes will not be liable to drop out during transportation.

In the accompanying drawings, Figure 1 represents a front view of a machine which embodies our invention. Figs. 2 and 3 show sections of dies.

A represents a suitable base or stand, and into the top of which is screwed or otherwise secured the lower portion B of the tubular body. This portion B is larger than the upper portion 0, which is secured to its upper end, and adjustably fastened to this body B at any desired point is a table or support D, upon or in which the lower die G is placed. This table or support D has an opening through it at one end, so that it can be adjusted freely upon the body B according to the length of tube which is to be crimped or to suit the height of the operator. The die G has a concave or other suitably-shaped groove formed in it for the purpose of crimping or turning in the lower edges of the tubes. This support or table D is secured in any desired position by means of a set-screw H, which passes through the tubular portion of the table or support and clamps against the side of the body B.

Passing down through the top of the lower portion B of the body is the upper portion 0, which has a greater length, but is just enough smaller than the portion 13 to move freely up and down through it. To the end of this portion 0 is attached a cap I, to which the upper end of the treadle-rod J is secured, and around this treadle-rod, inside of the body B and above the top of the support A, is placed a spiral spring L, by means of which the upper portion 0 of the body is returned to position after the treadle N has been depressed. To the upper end of this portion 0 of the body is secured a second support 0, which has a die P secured to or formed in its under surface, and which die crimps or turns in the upper ends of the tubes. This support 0 is also clamped in any desired position, according to the length of the tubes to be crimped, by means of a set-screw Q.

The ends of the tubes are placed in a line with the two dies G P, and then the treadle is compressed, the upper die P being forced downward toward the lower die G, and thus both ends of the tube are crimped at the same time.

In order to center the ends of the tubes and prevent them get-ting out of line with the dies after the operator begins to compress the treadle N, a flange R of suitable length is formed on the under side of this support 0 and on the upperside of the one D, and it is only necessary to place the tubes inside of the concaved portions of these flanges B, when it will be found that they are in the proper position when the upper die begins to compress the tube endwise.

As shown in Figs. 2 and 3, the recess in the dies maybe either conical or angular, as may be preferred. We do not limit ourselves to any particular form of dies, for this may be varied without departing from the spirit of our invention.

If so desired, before the tube is crimped a disk T, made of paper, sheet metal, or any other suitable material, may be placed in each end of the tube, so as to prevent the article in the tube from dropping out, and then the crimping of the ends of the tube prevents the disks from dropping out. Where these disks are used, a large number of small articles can be placed in a tube for transportation through the mails with perfect safety.

Having thus described our invention, We claim p 1. The combination of the tubular body B, mounted upon a suitable stand or support, and a lower support or table Which is attached thereto, with the upper portion of the frame,

the upper support placed thereon, and a spring-actuated treadle mechanism for depressing the upper die upon the lower one, substantially as shown.

2. In a machine for crimping the ends of paper tubes, the combination of the two sup ports secured to a suitable frame and made vertically movable in relation to each other, each one being provided with a circular flange for the purpose of centering the tube in position, with the dies for crimping the ends of the tubes, substantially as set forth.

In testimony whereof We affix our signatures in presence of tWo witnesses.
